As the $315-million renovation to the nearly 100-year-old Los Angeles Memorial Coliseum heads toward the end zone, more than 400 workers per day are navigating complex logistics and differing as-builts to complete the project in time for the LA Rams’ preseason game against the Denver Broncos on Aug. 24.

Because of the Coliseum’s location, and the fact that construction has to revolve around two active football teams, the challenges have been amplified, says Jeff Moe, onsite manager of construction for the University of Southern California, which is overseeing the renovation.
